Attached are three PDF files which contain the SIDRA Roundabout Analysis for: • Rahling Road at Pebble Beach Drive • Rahling Road at Wellington Plantation Drive • Wellington Plantation Drive and Beckenham Drive. The geometry, LOS and queue analysis is included for each intersection in the respective files. The LOS and queuing look good for each intersection if the City elects to construct roundabouts at these locations.
